摘要

A scheme for the computation of internal forces of large diameter pile has been devised in this paper on the basis of the generalized displacement model. The numerical results of large diameter pile under typical load case suggest that the dimension and structural mechanical characteristic of the large diameter pile can exert very strong influence on the pile soil interaction, hence it is an nonnegligible factor that should be taken seriously in the design of the pile foundation.
